DuPont tau tsim patented thev naus laus zis rau kev sib xyaw thiab ua cov fluoropolymer foam resins.Cov txheej txheem ua npuas ncauj koom nrog kev txhaj tshuaj tas li ntawm cov roj xws li nitrogen ncaj qha rau hauv extruder uas muaj cov molten resin.Ib qho tshwj xeeb tsim extruder ntsia hlau feem ntau yog siv los tsim cov roj polymer sib xyaw nrog cov pob inert nucleating muaj nyob rau hauv cov resin los pab txhawb kev loj hlob ntawm tes.Ua npuas ncauj txog li 60% voids tau pom los ntawm kev siv cov txheej txheem no.
Daim ntawv thov rau Melt Processable Perfluorinated Resins
FEP thiab PFA perfluorinated resins muaj yaj viscosities tsawg txaus rau kev ua hauv yaj extruders.Tsis tas li ntawd, FEP thiab PFA tau zoo haum rau extrusion foaming thaum tuav lawv cov dielectric tsis tu ncua thiab tsis tshua muaj dissipation yam, ob qho tib si tsim nyog rau twisted khub thiab coaxial cable rwb thaiv tsev.
Cov ntaub ntawv cables yog siv nyob rau hauv kev xa xov hluav taws xob hauv ntau qhov chaw thiab kev siv.Cov khoom hluav taws xob tseem ceeb uas yuav tsum tau muaj rau cov cables no suav nrog qhov tsis tshua muaj dielectric tsis tu ncua thiab tsis muaj qhov cuam tshuam tsawg.Cov khoom no tuaj yeem txhim kho los ntawm foaming lub rwb thaiv tsev.Raws li cov resin siv, cables muaj ib tug foamed rwb thaiv tsev tso cai cable miniaturization, hnyav txo ntawm cov khoom kawg, thiab cov kis tau tus mob ntawm cov high-zoo hluav taws xob teeb liab ntawm high teeb liab speeds.
Foamed cables fabricated los ntawm DuPont fluoropolymer resins tau dhau los ua neeg nyiam heev hauv computer manufacturing thiab installation ntawm network systems.Cables ua nrog FEP lossis PFA muaj cov nplaim hluav taws tsawg thiab cov pa luam yeeb tsawg.Cov kab hluav taws xob no tuaj yeem hla dhau los ntawm plenums thiab lwm yam huab cua tuav ducts, txo qhov kev xav tau ntawm cov khoom siv hluav taws xob kim.
Cov qauv thiab cov khoom ntawm Fluoropolymers
Qhov kev tshawb pom ntawm PTFE los ntawm DuPont tau tshwm sim hauv xyoo 1930's, tab sis lub sijhawm ntawd, cov tshuaj perfluorinated tshiab tsis tuaj yeem yaj extruded.Kev tshawb fawb ntxiv los ntawm DuPont rau hauv kev hloov kho ntawm cov txheej txheem polymer coj mus rau kev txhim kho cov txheej txheem ntawm cov txheej txheem fluoropolymer xws li FEP, PFA, thiab ETFE, solidifying DuPont ua tus thawj coj hauv ntiaj teb hauv kev tshawb fawb fluoropolymer.
Lub peev xwm yaj extrude cov polymers, ua ke nrog cov yam ntxwv xws li tsis tshua muaj hluav taws xob tsis tu ncua thiab tsis tshua muaj hluav taws xob ua rau FEP thiab PFA zoo haum rau kev siv hlau thiab cable.
